While opening a company file, QuickBooks closes if there is an issue with the company file itself or with the application. You can solve this issue by following the procedures indicated below: 1. To find and correct any issues, use the QuickBooks File Doctor application. 2. Make sure the file size is not unreasonably large. 3. Check the file path to ensure it is legitimate. 4. Confirm that the QuickBooks software is up-to-date and that all updates have been deployed. 5. Verify that the file is not corrupted by using the Check and Rebuild Data programmes. Try opening the company file in a different QuickBooks edition. 7. Try opening the corporate document on a another machine. https://www.storybaaz.com/article/quickbooks-closes-when-opening-company-file/hcLzv1hFM2LgF5SIQl0Y
